Endometrial carcinomas in the isthmus are called lower uterine segment (LUS) cancers. It is a rare location among uterine cancers and is known to be associated with Lynch syndrome, which tends to occur at a young age. Preoperative diagnosis may be difficult due to its anatomical location, and the prognosis is poorer than that of uterine cancer in general.

Background: We have previously shown that dyssynchronous premature atrial complexes (PACs) from the lateral left atrium (LA) lead to greater atrial mechanical dysfunction, remodeling, and sustained atrial fibrillation (AF) than synchronous PACs from the interatrial septum. However, the impact of PAC coupling interval (CI) on atrial remodeling is unclear.

Objectives: This study sought to explore the effect of PAC CI on atrial mechanics and remodeling in the swine model.

Article Synopsis
  • GDF15 and FGF21 are liver-secreted cytokines that show potential as treatments for metabolic dysfunction-associated steatotic liver disease (MASLD), but their interaction is not fully understood.
  • Overexpressing GDF15 or FGF21 in mice on a high-fat diet led to reduced body weight, fat mass, and insulin resistance, with GDF15 also lowering weight without affecting food intake.
  • GDF15 may enhance fatty acid metabolism and induce FGF21 expression through specific cellular mechanisms, indicating that their interaction is significant for addressing MASLD.

The stereoselective activation of alkanes constitutes a long-standing and grand challenge for chemistry. Although metal-containing enzymes oxidize alkanes with remarkable ease and selectivity, chemical approaches have largely been limited to transition metal-based catalytic carbon-hydrogen functionalizations. Alkanes can be protonated to form pentacoordinated carbonium ions and fragmented into smaller hydrocarbons in the presence of strong Brønsted acids.
